Ergonomically designed portable cooling seat

ABSTRACT

An ergonomically designed portable cooling seat is provided. The portable cooling seat according to current application is comprised of a flexible connection duct, a flexible air distributor that is in a form of plastic cushion, a tiny blower that installed inside of the connection duct to facilitate introduction of air from air-conditioner into the air distributor, and a solid structure that is foldable along the center thereof. The air distributor and the solid foldable structure are ergonomically designed and covered with soft clothes to form a portable cooling seat. The portable cooling seat supplies cool air to the back and beneath of the buttocks of a driver, while avoiding undesirable region such as perinea and shoulder, to prevents driver&#39;s body oozed by sweat.

FIELD OF THE INVENTION

Current application relates to a portable seat, especially relates to an ergonomically designed portable seat that supplies cool air from air-conditioner of a car into gaps between back and bottom of a driver and driver's seat of a car, except perinea area and shoulder.

BACKGROUND OF THE INVENTION

Most of modern passenger cars are equipped with air-conditioner combined with heater. Outlets of the cooled/heated air are developed on many points inside of a car. The air circulation system of a car is designed to circulate the air inside of a car swiping every corner of the indoor. On a hot summer day, most of drivers close the windows and turn on air-conditioner. However, sometimes, they want open the window for fresh out door air. But, as soon as the window is open, all the cool air flushed out side. Some portable seats are provided to keep the driver's seat cool. However, they are designed without any consideration about medical effects of cold air on a human body. It is well known for oriental medical science that long exposure of perinea area to cold temperature may worse hemorrhoids for men and leucorrhea of women. And direct contact to shoulder also worse frozen shoulder. It is purpose of the current application to provide a portable seat that is designed ergonomically to avoid such defects of the prior arts while supplying cool air from air-conditioner to the back and underneath of buttocks of a driver to prevent the driver's body oozed by sweats after long hours drive on a hot summer day.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

FIG. 1 is a perspective view of a portable cooling seat (1) according to current application. And FIG. 2 is an exploded view of the portable cooling seat (1) of the current application. The portable cooling seat (1) according to current application is comprised of a flexible connection duct (2), a flexible air distributor (3) that is in a form of plastic cushion, a tiny blower (2-1) that installed inside of the connection duct to facilitate introduction of air from air-conditioner's outlet (5) into the air distributor, and a solid structure (4) that is foldable along the center thereof. One end of the flexible connection duct (2-2) is connected to inlet (3-1) of the flexible air distributor (3) and the other end (2-3) is connected to the air-conditioner's outlet (5) of a car. The air distributor (3) and the solid foldable structure (4) are ergonomically designed and covered with soft clothes (6) to form a portable cooling seat followed by stitching the clothes (6) along the brim (7) thereof. Front layer (6-1) of the clothes (6) is porous mesh and rear layer (6-2) is non porous. The air distributor (3) is supported by a solid supporting structure (4) that is foldable along the center thereof. The solid supporting structure (4) is made of a stiff plastic sheet of 2 mm thick. Pluralities of square air windows (4-1) are developed on the solid supporting structure (4) surrounding pluralities of protrusions (4-2), which poke out to car's seat side. The air windows (4-1) are not developed on the area (4-3) with which driver's shoulders contact and the area (4-4) with which perinea area of the driver contacts. The air distributor (3) is made of flexible plastic in a shape of a toy tube for swimming. Pluralities of square air screen windows (3-2) are developed on the front face (3-3) of the air distributor (3) surrounding pluralities of cylindrical holes (3-4), which connect the front face (3-3) and rear face (3-5) of the air distributor (3). The air screen windows (3-2) are not developed on the area (3-6) on which driver's shoulders place and the area (3-7) on which perinea area of the driver places.

FIG. 3 is an enlarged view of section ‘C’ in FIG. 2 showing square air window (4-1) and protrusions (4-2) of the supporting structure (4). Four square air windows (4-1) are developed surrounding one protrusion. FIG. 4 is an enlarged view of section ‘D’ in FIG. 2 showing square air screen windows (3-2) and cylindrical holes (3-4) to receive the protrusion (4-2). Four square air screen windows (3-2) are developed surrounding one cylindrical hole (3-4).

FIG. 5 is an enlarged perspective view of section ‘E’ in FIG. 2 showing three dimensional structure of the air distributor (3). The cylindrical holes (3-4) are developed penetrate the air distributor (3). Therefore, wall (3-8) of the cylindrical hole (3-4) blocks and changes pass way of cool air (8) from the outlet (5) of the car's air-conditioner. Walls (3-8) of the cylindrical holes (3-4) distribute the cool air (8) throughout inside of the air distributor (3).

FIG. 6 is a cross sectional view along line A-A′ of the portable cooling seat (1), according to current application, seen from view point A″ in FIG. 2. Line A-A′ in FIG. 2 are marked on the covering clothes (6), the supporting structure (4), and the air distributor (3) because they are actually over-lapped. The supporting structure (4) is overlapped on the air distributor (3) by inserting the protrusions (4-2) of the supporting structure (4) into the cylindrical holes (3-4) of the air distributor (3) on matching position. FIG. 7 is a cross sectional view along line B-B′ of the portable cooling seat seen from view point B″ in FIG. 2. Line B-B′ in FIG. 2 is marked on the covering clothes (6), the supporting structure (4), and the air distributor (3) because they are actually over-lapped. Cool air (8), came from an outlet (5) of car air-conditioner, is distributed through the air distributor (3) by the walls (3-8) of cylindrical holes (3-4) and reach the air screen holes (3-2). The air hole (3-2) is screened to develop some pressure inside of the air distributor (3). The pressured air distributor (3) provides a cushion to the seat (1). The cool air (8), then pass the square holes (4-1) and spreads and passes through the pores of the front face (6-1) of the seat (1). Positions of the air screen holes (3-2) and square holes (4-1) block the cool air (8) from supplied to perinea area and shoulder of a driver.
